Description

Technical Field

[0001] This utility model relates to the field of food additive extraction technology, specifically a rapid extraction device for food additive detection. Background Technology

[0002] Food additives are artificial or natural substances added to food to improve its color, aroma, and taste, as well as for preservation and processing needs. Currently, food additives in my country include acidity regulators, anti-caking agents, defoamers, antioxidants, bleaching agents, leavening agents, coloring agents, and flavorings. Excessive use of these food additives can cause harm to the human body; therefore, it is necessary to conduct appropriate testing on the content of food additives.

[0003] The prior art, disclosed in CN216746950U, provides a rapid extraction device for food additive detection, including a workbench. A support frame is bolted to one side of the upper surface of the workbench. A liquid extraction tube is fixedly installed on the upper surface of the support frame, and a rubber hose is fixedly installed on the lower surface of the liquid extraction tube. The end of the rubber hose away from the liquid extraction tube passes through the upper surface of the support frame. A first control valve is fixedly installed on one side wall of the liquid extraction tube. An external thread is formed on the upper part of the outer wall of the liquid extraction tube, and a liquid extraction cylinder is located above the liquid extraction tube. The advantages of this invention are: by setting up a liquid extraction tube, a rubber hose, a first control valve, a liquid extraction cylinder, a piston, a push rod, a push block, a liquid outlet tube, and a second control valve, this device not only avoids contact between liquid food additives and air, improving the detection effect of liquids, but also has a simple structure, is easy to operate, and has high extraction efficiency.

[0004] The aforementioned patent primarily uses the movement of a sealed piston to extract liquid food additives. However, this method of extracting food additives requires manual operation of the push block by the user throughout the process, making the extraction process for food additive detection quite cumbersome and significantly reducing the practicality of the rapid extraction device for food additive detection. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid extraction device for food additive detection, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid extraction device for food additive detection, comprising a device body, a central controller and an adjustment assembly fixedly mounted on the top of the device body. The central controller controls the electronic components within the extraction device. An extraction assembly for food additive extraction is movably mounted on the adjustment assembly. The device body includes a support frame with a top window for moving the extraction assembly. A rotation assembly is fixedly mounted within the support frame for storing and collecting the extracted food additives. The extraction assembly includes a hollow cylinder for temporary storage of the food additives. A piston for extracting air from the hollow cylinder is movably mounted within the cylinder. A hollow needle is installed at the bottom of the hollow cylinder. The hollow needle at the bottom of the hollow cylinder allows for rapid extraction of food additives, significantly improving the extraction efficiency of the rapid extraction device for food additive detection.

[0007] Furthermore, a sealing gasket is provided in the middle of the piston, and the sealing gasket fits against the inner wall of the hollow cylinder. A movable shaft is fixedly connected to the end of the piston away from the hollow needle tube. The movable shaft is movably located at the top of the hollow cylinder. A fixed plate is fixedly connected to the end of the movable shaft away from the piston. The fixed plate assists the movement of the movable shaft and the piston, thereby making the piston move more conveniently and quickly, and improving the overall automation of the rapid extraction device for food additive detection.

[0008] Furthermore, the adjustment assembly includes a hydraulic push rod fixedly mounted on the support frame. A connecting strip is fixedly mounted on the output end of the hydraulic push rod, and a fixing component for fixing the extraction assembly is fixedly connected to the connecting strip. The hydraulic push rod is used to control the overall extension and retraction of the extraction assembly. This control of the extension and retraction of the extraction assembly significantly improves the overall integrity of the internal structure of the rapid extraction device for food additive detection.

[0009] Furthermore, the hollow cylinder has embedding grooves on both sides of its exterior. The fixing assembly includes a first arc strip fixedly connected to the connecting strip. A fixing cylinder is fixedly installed on one side of the first arc strip. A rotating shaft is rotatably installed inside the fixing cylinder. A second arc strip is fixedly installed on the rotating shaft. A locking assembly is fixedly installed on the side of the first arc strip away from the fixing cylinder.

[0010] Furthermore, a sub-controller is fixedly installed at the end of the connecting strip furthest from the hydraulic push rod. The sub-controller is electrically connected to the main controller. An electric push rod is fixedly connected to the output end of the sub-controller. A locking element is fixedly installed at the telescopic end of the electric push rod, and the fixed disc is located in the middle of the locking element.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application provides a further detailed description. A rapid extraction device for food additive detection includes a device body 1. A master controller 2 and an adjustment assembly 3 are fixedly installed on the top of the device body 1. The master controller 2 is used to control the electronic components inside the extraction device. An extraction assembly 4 for food additive extraction is movably installed on the adjustment assembly 3. The device body 1 includes a support frame 12. A top window 11 for moving the extraction assembly 4 is opened on the top of the support frame 12. A replacement assembly 13 is fixedly installed inside the support frame 12. The replacement assembly 13 is used for storing food additives and collecting food additives after extraction. The extraction assembly 4 includes a hollow cylinder 45 for temporary storage of food additives. A piston 46 for extracting air from the hollow cylinder 45 is movably installed inside the hollow cylinder 45. The bottom of the hollow cylinder 45... The hollow cylinder 45 is equipped with a hollow needle tube 47. A sealing gasket 44 is provided in the middle of the piston 46, and the sealing gasket 44 fits against the inner wall of the hollow cylinder 45. A movable shaft 42 is fixedly connected to the end of the piston 46 away from the hollow needle tube 47. The movable shaft 42 is movably located at the top of the hollow cylinder 45. A fixed plate 41 is fixedly connected to the end of the movable shaft 42 away from the piston 46. The fixed plate 41 is used to assist the movement of the movable shaft 42 and the piston 46. The adjusting component 3 includes a hydraulic push rod 31 fixedly installed on the support frame 12. A connecting strip 32 is fixedly installed on the output end of the hydraulic push rod 31. A fixing component 36 for fixing the extraction component 4 is fixedly connected to the connecting strip 32. The hydraulic push rod 31 is used to control the overall extension and retraction of the extraction component 4. The hollow cylinder 45 has embedded openings on both sides of its exterior. The groove 43 and the fixing assembly 36 include a first arc strip 361 fixedly connected to the connecting bar 32. A fixing cylinder 366 is fixedly installed on one side of the first arc strip 361. A rotating shaft 365 is rotatably installed inside the fixing cylinder 366. A second arc strip 364 is fixedly installed on the rotating shaft 365. A locking assembly 362 is fixedly installed on the side of the first arc strip 361 away from the fixing cylinder 366. The locking assembly 362 is used for detachable installation of the first arc strip 361 and the second arc strip 364. A retaining block 363 is fixedly installed at the center of the inner wall of the second arc strip 364. The retaining block 363 is used to embed into the retaining groove 43. A sub-controller 33 is fixedly installed at the end of the connecting bar 32 away from the hydraulic push rod 31. The sub-controller 33 is electrically connected to the main controller 2. The output end of the sub-controller 33 is fixed. An electric push rod 34 is connected, and a locking member 35 is fixedly installed at the telescopic end of the electric push rod 34. The fixed plate 41 is located in the middle of the locking member 35. The electric push rod 34 is used to control the movement of the movable shaft 42. The rotating assembly 13 includes a motor 132 fixedly installed at the bottom of the support frame 12. The control box of the motor 132 is electrically connected to the main controller 2. A turntable 135 is fixedly installed at the output end of the motor 132. A collection bottle 131 and a material bottle 134 are fixedly arranged on the turntable 135. The collection bottle 131 and the material bottle 134 are symmetrically located on both sides of the turntable 135. A spectrophotometer 133 for food additive detection is fixedly installed on the collection bottle 131. The extraction assembly 4 is located directly below the rotation trajectory of the collection bottle 131 and the material bottle 134.

[0025] Since the locking component 35 is in the shape of two fixed forks, and the fixed plate 41 is in the shape of a disc, the two forks of the locking component 35 are directly distributed on the upper and lower sides of the fixed plate 41 during installation. At this time, when the electric push rod 34 moves the locking component 35 up and down, the movable shaft 42 and the piston 46 can be moved up and down directly through the fixed plate 41.

[0026] The main controller 2 has a microcontroller and a Bluetooth module inside, and the sub-controller 33 also has a microcontroller and a Bluetooth module inside. The main controller 2 and the sub-controller 33 are remotely connected through the Bluetooth module. Therefore, the main controller 2 can directly control the electronic components in the rapid extraction device used for food additive detection.

[0027] The working principle of the extraction component 4 is the same as that of the syringe used for injection. Since the sealing gasket 44 inside the piston 46 is tightly attached to the inner wall of the hollow cylinder 45, the hollow cylinder 45 can be vented and evacuated when the piston 46 moves. Since the hollow syringe 47 is a hollow tube, the liquid sucked into the hollow cylinder 45 will temporarily remain inside the hollow cylinder 45 due to atmospheric pressure, and can only be released by the downward movement of the piston 46.

[0028] Since the second arc bar 364 can swing around the pivot 365 on the first arc bar 361, and the locking assembly 362 locks and fixes the first arc bar 361 and the second arc bar 364 by bolts, and the embedding block 363 can be directly inserted into the embedding groove 43 for upper and lower limit fixation, the fixing assembly 36 can directly fix the extraction assembly 4 in a detachable manner.

[0029] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the rapid extraction device for food additive detection are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. During use, the user places the liquid food additive to be extracted into the material bottle 134. The motor 132 moves the material bottle 134 directly below the hollow needle tube 47. At this time, the main controller 2 controls the hydraulic push rod 31 to retract, allowing the hollow needle tube 47 to insert into the material bottle 134. Simultaneously, the sub-controller 33 controls the electric push rod 34 to move the movable shaft 42 upwards. The air removed from the material bottle 134 is drawn directly into the hollow cylinder 45. Then, the hydraulic push rod 31 moves upward, and the motor 132 controls the turntable 135 to continue rotating, positioning the collection bottle 131 directly below the hollow syringe 47. At this point, the hydraulic push rod 31 moves downward, followed by the electric push rod 34, allowing the extracted liquid food additive to directly enter the collection bottle 131 for collection. The sample is then detected by a spectrophotometer 133. This combination of structures allows users to extract and detect liquid food additives more conveniently and quickly, greatly improving the practicality of the rapid extraction device for food additive detection.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
